DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] refer to Figures 1 to 4 A raw material mixing device comprises a frame 1, a mixing barrel 2 and a mixing mechanism 3, wherein the mixing barrel 2 is rotatably connected in the frame 1; a driving mechanism 11 for driving the mixing barrel 2 to rotate is arranged in the frame 1; one end of the mixing mechanism 3 is connected to the frame 1, and the other end is located in the mixing barrel 2; a temperature control mechanism 12 is arranged on the frame 1, and a temperature regulating part 321 connected to the temperature control mechanism 12 is arranged in the mixing mechanism 3; a feeding port 13 and a discharge pipe 14 for connecting the mixing barrel 2 with the outside are also arranged on the top of the frame 1.

[0028] Under this design, the operator adds the materials to be mixed into the mixing barrel 2 from the feeding port 13 in sequence, and then drives the mixing barrel 2 to rotate through the driving mechanism 11. The materials are driven by the mixing barrel 2 to form a vortex and collide with the stirring mechanism 3 to be mixed. During the stirring process, for a mixing environment that needs to be cooled, the friction between the material and the mixing barrel 2, and the friction between the material and the stirring mechanism 3 will increase the temperature of the material. At this time, in order to avoid affecting the mixing quality of the materials, the operator can adjust the temperature of the temperature regulating part 321 in the stirring mechanism 3 through the temperature control mechanism 12 to cool the materials in time; for a mixing environment that needs to be heated and kept at a constant temperature, the operator can also adjust the temperature of the temperature regulating part 321 in the stirring mechanism 3 through the temperature control mechanism 12 to reduce the temperature difference between the stirring mechanism 3 and the materials and improve the mixing efficiency.

[0029] In this embodiment, the frame 1 includes an outer barrel 15, a support base 16 connected to the bottom of the outer barrel 15, and a support frame 17 connected to the top of the outer barrel 15. The driving mechanism 11 is located in the support base 16, the mixing barrel 2 is located in the outer barrel 15, and the bottom of the mixing barrel 2 is connected to the driving mechanism 11, the temperature control mechanism 12 is connected to the support frame 17, the feeding port 13 is located on the support frame 17, and the discharge pipe 14 is movably connected to the support frame 17.

[0030] The outer barrel 15 and the support seat 16 both play a protective role. First of all, the outer barrel 15 can not only protect the mixing barrel 2, because the mixing barrel 2 is rotating. In the absence of the outer barrel 15, the rotating mixing barrel 2 will be exposed to the processing environment, which increases the danger of the processing environment. The addition of the outer barrel 15 can prevent the staff from accidentally touching the mixing barrel 2; and the support seat 16 plays the same role. While protecting the driving mechanism 11, it can also prevent the staff from accidentally contacting the driving mechanism 11.

[0031] Preferably, the stirring mechanism 3 includes a bracket 31 and a stirring plate 32 , the top end of the bracket 31 is connected to the temperature control mechanism 12 , and the bottom end of the bracket 31 is suspended in the stirring barrel 2 , the stirring plate 32 is symmetrically arranged and connected to the bracket 31 , and the temperature regulating part 321 is located in the stirring plate 32 .

[0032] In actual work, because the stirring mechanism 3 is stationary, the stirring plate 32 needs to withstand the impact of the vortex material. By adding the bracket 31, the stability of the stirring plate 32 can be ensured; and the temperature regulating part 321 is set in the stirring plate 32, which can better protect the temperature regulating part 321 and avoid direct collision between the temperature regulating part 321 and the material. In addition, the stirring plate 32 can also increase the contact area with the material to ensure the quality of material mixing.

[0033] Optionally, the bracket 31 is a cross-shaped structure, and the bracket 31 includes an integrally formed cross bar 311 and a vertical bar 312, one end of the vertical bar 312 is connected to the temperature control mechanism 12, and the other end of the vertical bar 312 passes through the mixing barrel 2 and the driving mechanism 11 in sequence and is connected to the support seat 16; the vertical bar 312 is movably connected to the mixing barrel 2 and the driving mechanism 11, one end of the stirring plate 32 is connected to the vertical bar 312, and one side of the stirring plate 32 is connected to the cross bar 311.

[0034] Specifically, the bracket 31 is not limited to a cross-shaped structure. The cross-shaped structure is adopted in this embodiment because it can maximize the use of the structure. In short, one end of the vertical rod 312 is connected to the temperature control mechanism 12, and the other end passes through the mixing barrel 2 and the driving mechanism 11 in sequence, and is connected to the support seat 16; while ensuring the stability of the vertical rod 312, because the vertical rod 312 is stationary during the mixing process, the vertical rod 312 is movably connected with the mixing barrel 2 and the driving mechanism 11, which is equivalent to acting as the axis of the mixing barrel 2, ensuring the stability of the rotation of the mixing barrel 2. The role of the cross bar 311 is to ensure the stability of the mixing plate 32. Through the cooperation of the cross bar 311 and the vertical rod 312, the mixing plate 32 is supported both horizontally and vertically.

[0035] Optionally, in this embodiment, the temperature control mechanism 12 and the temperature adjustment part 321 may adopt a combination of a hot and cold water circulation pump and a pipeline, or may adopt a combination of a temperature controller and a semiconductor component.

[0036] As for the combination of the hot and cold water circulation pump and the pipeline, the temperature control mechanism 12 is a hot and cold water circulation pump, which is connected to the support frame 17; the temperature adjustment part 321 is a pipeline, which is connected to the hot and cold water circulation pump, and the pipeline is located in the stirring plate 32. In actual use, according to different mixing environments, the hot and cold water circulation pump adjusts the temperature of the pipeline by controlling the ratio of cold water and hot water, thereby adjusting the temperature of the stirring plate 32.

[0037] Regarding the combination of the temperature controller and the semiconductor component, the temperature control mechanism 12 is a temperature controller, which is connected to the support frame 17; the temperature adjustment part 321 is a semiconductor component, which is electrically connected to the temperature controller, and the semiconductor component is located in the stirring plate 32. In actual use, according to different mixing environments, the temperature controller controls the temperature of the semiconductor component to adjust the temperature of the stirring plate 32.

[0038] For these two combinations, the combination structure of the hot and cold water circulation pump and the pipeline is simpler, and the pipeline can flow through most areas of the stirring plate 32, making the temperature of the stirring plate 32 more uniform; and although the combination of the temperature controller and the semiconductor component is convenient, accurate and fast to control, when the area of ​​the stirring plate 32 is too large, the arrangement of the semiconductor component is relatively troublesome, so this embodiment adopts a combination method in which the temperature control mechanism 12 is a hot and cold water circulation pump and the temperature adjustment part 321 is a pipeline.

[0039] In this embodiment, the mixing barrel 2 includes a pulsator base 21 and a barrel body 22 connected to the pulsator base 21. The pulsator base 21 is connected to the driving mechanism 11, and the top of the barrel body 22 is open. When the mixing barrel 2 and the pulsator base 21 rotate, the material forms a vortex in the mixing barrel 2 under the drive of the pulsator base 21, and collides with the stirring plate 32 to achieve a mixing effect.

[0040] Preferably, the vertical cross section of the impeller base 21 is funnel-shaped. In actual use, the vertical cross section of the impeller base 21 is funnel-shaped, that is, the impeller base 21 as a whole is close to the shape of a cone, so that the center of gravity and the axis of the impeller base 21 coincide, and it is more stable when rotating.

[0041] Preferably, the driving mechanism 11 includes a driving motor 111 connected to the frame 1, a synchronous wheel module 112 connected to the driving motor 111, and a impeller shaft 211 is provided at the bottom of the impeller base 21, and the impeller shaft 211 is connected to the synchronous wheel module 112. When in use, the driving motor 111 drives the synchronous wheel module 112 to work, and the synchronous wheel module 112 drives the impeller shaft 211 to drive the impeller base 21 to rotate, so as to realize the rotation of the mixing barrel 2. The synchronous wheel module 112 has good transmission stability, can reduce the impact and vibration during transmission, and improve the stability of the mixing barrel 2. The synchronous wheel module 112 has been disclosed in Chinese patent CN109236960A, so the structure of the synchronous wheel module 112 is not described in detail in this embodiment.

[0042] Preferably, the frame 1 further comprises a fixing frame 18, a plurality of connecting columns 181 are provided on the top of the fixing frame 18, a plurality of connecting plates 151 corresponding to the plurality of connecting columns 181 are provided on the outer side of the outer barrel 15, the plurality of connecting columns 181 are respectively connected to the plurality of connecting plates 151, and the support seat 16 is fitted with the top of the fixing frame 18. The fixing frame 18 can lift the support seat 16 off the ground, because during the mixing process, the support seat 16 and the outer barrel 15 will vibrate, and after lifting off the ground, the vibration can be prevented from being transmitted to the processing site.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
